Property Descriptions

• Color albedo_color

The material’s base color.

• Texture albedo_texture

Texture to multiply by albedo_color. Used for basic texturing of objects.

• float anisotropy

The strength of the anisotropy effect.

• bool anisotropy_enabled

If true, anisotropy is enabled. Changes the shape of the specular blob and aligns it to tangent space. Mesh tangents are needed for this to work. If the mesh does not contain tangents the anisotropy effect will appear broken.

• Texture anisotropy_flowmap

Texture that offsets the tangent map for anisotropy calculations.

• bool ao_enabled

If true, ambient occlusion is enabled. Ambient occlusion darkens areas based on the ao_texture.

• float ao_light_affect

Amount that ambient occlusion affects lighting from lights. If 0, ambient occlusion only affects ambient light. If 1, ambient occlusion affects lights just as much as it affects ambient light. This can be used to impact the strength of the ambient occlusion effect, but typically looks unrealistic.

• bool ao_on_uv2

If true, use UV2 coordinates to look up from the ao_texture.

• Texture ao_texture

Texture that defines the amount of ambient occlusion for a given point on the object.

• TextureChannel ao_texture_channel

Specifies the channel of the ao_texture in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• float clearcoat

Sets the strength of the clearcoat effect. Setting to 0 looks the same as disabling the clearcoat effect.

• bool clearcoat_enabled

If true, clearcoat rendering is enabled. Adds a secondary transparent pass to the lighting calculation resulting in an added specular blob. This makes materials appear as if they have a clear layer on them that can be either glossy or rough.

Note: Clearcoat rendering is not visible if the material has flags_unshaded set to true.

• float clearcoat_gloss

Sets the roughness of the clearcoat pass. A higher value results in a smoother clearcoat while a lower value results in a rougher clearcoat.

• Texture clearcoat_texture

Texture that defines the strength of the clearcoat effect and the glossiness of the clearcoat. Strength is specified in the red channel while glossiness is specified in the green channel.

• bool depth_deep_parallax

If true, the shader will read depth texture at multiple points along the view ray to determine occlusion and parrallax. This can be very performance demanding, but results in more realistic looking depth mapping.

• bool depth_enabled

If true, depth mapping is enabled (also called “parallax mapping” or “height mapping”). See also normal_enabled.

Note: Depth mapping is not supported if triplanar mapping is used on the same material. The value of depth_enabled will be ignored if uv1_triplanar is enabled.

• bool depth_flip_binormal

If true, direction of the binormal is flipped before using in the depth effect. This may be necessary if you have encoded your binormals in a way that is conflicting with the depth effect.

• bool depth_flip_tangent

If true, direction of the tangent is flipped before using in the depth effect. This may be necessary if you have encoded your tangents in a way that is conflicting with the depth effect.

• int depth_max_layers

Number of layers to use when using depth_deep_parallax and the view direction is perpendicular to the surface of the object. A higher number will be more performance demanding while a lower number may not look as crisp.

• int depth_min_layers

Number of layers to use when using depth_deep_parallax and the view direction is parallel to the surface of the object. A higher number will be more performance demanding while a lower number may not look as crisp.

• float depth_scale

Scales the depth offset effect. A higher number will create a larger depth.

• Texture depth_texture

Texture used to determine depth at a given pixel. Depth is always stored in the red channel.

• Texture detail_albedo

Texture that specifies the color of the detail overlay.

• BlendMode detail_blend_mode

Specifies how the detail_albedo should blend with the current ALBEDO. See BlendMode for options.

• bool detail_enabled

If true, enables the detail overlay. Detail is a second texture that gets mixed over the surface of the object based on detail_mask. This can be used to add variation to objects, or to blend between two different albedo/normal textures.

• Texture detail_mask

Texture used to specify how the detail textures get blended with the base textures.

• Texture detail_normal

Texture that specifies the per-pixel normal of the detail overlay.

Note: Godot expects the normal map to use X+, Y-, and Z+ coordinates. See this page for a comparison of normal map coordinates expected by popular engines.

• DetailUV detail_uv_layer

Specifies whether to use UV or UV2 for the detail layer. See DetailUV for options.

• float distance_fade_max_distance

Distance at which the object appears fully opaque.

Note: If distance_fade_max_distance is less than distance_fade_min_distance, the behavior will be reversed. The object will start to fade away at distance_fade_max_distance and will fully disappear once it reaches distance_fade_min_distance.

• float distance_fade_min_distance

Distance at which the object starts to become visible. If the object is less than this distance away, it will be invisible.

Note: If distance_fade_min_distance is greater than distance_fade_max_distance, the behavior will be reversed. The object will start to fade away at distance_fade_max_distance and will fully disappear once it reaches distance_fade_min_distance.

• DistanceFadeMode distance_fade_mode

Specifies which type of fade to use. Can be any of the DistanceFadeModes.

• Color emission

The emitted light’s color. See emission_enabled.

• bool emission_enabled

If true, the body emits light. Emitting light makes the object appear brighter. The object can also cast light on other objects if a GIProbe or BakedLightmap is used and this object is used in baked lighting.

• float emission_energy

The emitted light’s strength. See emission_enabled.

• bool emission_on_uv2

Use UV2 to read from the emission_texture.

• EmissionOperator emission_operator

Sets how emission interacts with emission_texture. Can either add or multiply. See EmissionOperator for options.

• Texture emission_texture

Texture that specifies how much surface emits light at a given point.

• bool flags_albedo_tex_force_srgb

Forces a conversion of the albedo_texture from sRGB space to linear space.

• bool flags_disable_ambient_light

If true, the object receives no ambient light.

• bool flags_do_not_receive_shadows

If true, the object receives no shadow that would otherwise be cast onto it.

• bool flags_ensure_correct_normals

If true, the shader will compute extra operations to make sure the normal stays correct when using a non-uniform scale. Only enable if using non-uniform scaling.

• bool flags_fixed_size

If true, the object is rendered at the same size regardless of distance.

• bool flags_no_depth_test

If true, depth testing is disabled and the object will be drawn in render order.

• bool flags_transparent

If true, transparency is enabled on the body. See also params_blend_mode.

• bool flags_unshaded

If true, the object is unaffected by lighting.

• bool flags_use_point_size

If true, render point size can be changed.

Note: this is only effective for objects whose geometry is point-based rather than triangle-based. See also params_point_size.

• bool flags_use_shadow_to_opacity

If true, enables the “shadow to opacity” render mode where lighting modifies the alpha so shadowed areas are opaque and non-shadowed areas are transparent. Useful for overlaying shadows onto a camera feed in AR.

• bool flags_vertex_lighting

If true, lighting is calculated per vertex rather than per pixel. This may increase performance on low-end devices.

• bool flags_world_triplanar

If true, triplanar mapping is calculated in world space rather than object local space. See also uv1_triplanar.

• float metallic

A high value makes the material appear more like a metal. Non-metals use their albedo as the diffuse color and add diffuse to the specular reflection. With non-metals, the reflection appears on top of the albedo color. Metals use their albedo as a multiplier to the specular reflection and set the diffuse color to black resulting in a tinted reflection. Materials work better when fully metal or fully non-metal, values between 0 and 1 should only be used for blending between metal and non-metal sections. To alter the amount of reflection use roughness.

• float metallic_specular

Sets the size of the specular lobe. The specular lobe is the bright spot that is reflected from light sources.

Note: unlike metallic, this is not energy-conserving, so it should be left at 0.5 in most cases. See also roughness.

• Texture metallic_texture

Texture used to specify metallic for an object. This is multiplied by metallic.

• TextureChannel metallic_texture_channel

Specifies the channel of the metallic_texture in which the metallic information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• bool normal_enabled

If true, normal mapping is enabled.

• float normal_scale

The strength of the normal map’s effect.

• Texture normal_texture

Texture used to specify the normal at a given pixel. The normal_texture only uses the red and green channels. The normal read from normal_texture is oriented around the surface normal provided by the Mesh.

Note: Godot expects the normal map to use X+, Y-, and Z+ coordinates. See this page for a comparison of normal map coordinates expected by popular engines.

• float params_alpha_scissor_threshold

Threshold at which the alpha scissor will discard values.

• bool params_billboard_keep_scale

If true, the shader will keep the scale set for the mesh. Otherwise the scale is lost when billboarding. Only applies when params_billboard_mode is BILLBOARD_ENABLED.

• BillboardMode params_billboard_mode

Controls how the object faces the camera. See BillboardMode.

Note: Billboard mode is not suitable for VR because the left-right vector of the camera is not horizontal when the screen is attached to your head instead of on the table. See GitHub issue #41567 for details.

• BlendMode params_blend_mode

The material’s blend mode.

Note: Values other than Mix force the object into the transparent pipeline. See BlendMode.

The number of horizontal frames in the particle sprite sheet. Only enabled when using BILLBOARD_PARTICLES. See params_billboard_mode.

• bool particles_anim_loop

If true, particle animations are looped. Only enabled when using BILLBOARD_PARTICLES. See params_billboard_mode.

• int particles_anim_v_frames

The number of vertical frames in the particle sprite sheet. Only enabled when using BILLBOARD_PARTICLES. See params_billboard_mode.

• float proximity_fade_distance

Distance over which the fade effect takes place. The larger the distance the longer it takes for an object to fade.

• bool proximity_fade_enable

If true, the proximity fade effect is enabled. The proximity fade effect fades out each pixel based on its distance to another object.

• bool refraction_enabled

If true, the refraction effect is enabled. Distorts transparency based on light from behind the object.

• float refraction_scale

The strength of the refraction effect.

• Texture refraction_texture

Texture that controls the strength of the refraction per-pixel. Multiplied by refraction_scale.

• TextureChannel refraction_texture_channel

Specifies the channel of the ao_texture in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• float rim

Sets the strength of the rim lighting effect.

• bool rim_enabled

If true, rim effect is enabled. Rim lighting increases the brightness at glancing angles on an object.

Note: Rim lighting is not visible if the material has flags_unshaded set to true.

• Texture rim_texture

Texture used to set the strength of the rim lighting effect per-pixel. Multiplied by rim.

• float rim_tint

The amount of to blend light and albedo color when rendering rim effect. If 0 the light color is used, while 1 means albedo color is used. An intermediate value generally works best.

• float roughness

Surface reflection. A value of 0 represents a perfect mirror while a value of 1 completely blurs the reflection. See also metallic.

• Texture roughness_texture

Texture used to control the roughness per-pixel. Multiplied by roughness.

• TextureChannel roughness_texture_channel

Specifies the channel of the ao_texture in which the ambient occlusion information is stored. This is useful when you store the information for multiple effects in a single texture. For example if you stored metallic in the red channel, roughness in the blue, and ambient occlusion in the green you could reduce the number of textures you use.

• Vector3 uv1_scale

How much to scale the UV coordinates. This is multiplied by UV in the vertex function.

• bool uv1_triplanar

If true, instead of using UV textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.

• float uv1_triplanar_sharpness

A lower number blends the texture more softly while a higher number blends the texture more sharply.

• Vector3 uv2_offset

How much to offset the UV2 coordinates. This amount will be added to UV2 in the vertex function. This can be used to offset a texture.

• Vector3 uv2_scale

How much to scale the UV2 coordinates. This is multiplied by UV2 in the vertex function.

• bool uv2_triplanar

If true, instead of using UV2 textures will use a triplanar texture lookup to determine how to apply textures. Triplanar uses the orientation of the object’s surface to blend between texture coordinates. It reads from the source texture 3 times, once for each axis and then blends between the results based on how closely the pixel aligns with each axis. This is often used for natural features to get a realistic blend of materials. Because triplanar texturing requires many more texture reads per-pixel it is much slower than normal UV texturing. Additionally, because it is blending the texture between the three axes, it is unsuitable when you are trying to achieve crisp texturing.

• float uv2_triplanar_sharpness

A lower number blends the texture more softly while a higher number blends the texture more sharply.

• bool vertex_color_is_srgb

If true, the vertex color is used as albedo color.

Method Descriptions

• bool get_feature ( Feature feature ) const

Returns true, if the specified Feature is enabled.

• bool get_flag ( Flags flag ) const

Returns true, if the specified flag is enabled. See Flags enumerator for options.

• Texture get_texture ( TextureParam param ) const

Returns the Texture associated with the specified TextureParam.

• void set_feature ( Feature feature, bool enable )

If true, enables the specified Feature. Many features that are available in SpatialMaterials need to be enabled before use. This way the cost for using the feature is only incurred when specified. Features can also be enabled by setting the corresponding member to true.

• void set_flag ( Flags flag, bool enable )

If true, enables the specified flag. Flags are optional behaviour that can be turned on and off. Only one flag can be enabled at a time with this function, the flag enumerators cannot be bit-masked together to enable or disable multiple flags at once. Flags can also be enabled by setting the corresponding member to true. See Flags enumerator for options.

• void set_texture ( TextureParam param, Texture texture )

Sets the Texture to be used by the specified TextureParam. This function is called when setting members ending in *_texture.
